I don't know of any surprises in my family.
On my father's side, his dad died when my dad was a teenager and his mother never remarried. So, there's my dad and his brother. The brother married and divorced once, has one kid, who is now in her 50s. She has a son about my age who now has two kids. I used to play with the son (my cousin) but haven't seen him for 25 years or so, other than being friends on Facebook.
On my mom's side, her parents were married for over 60 years before my grandfather died a couple of years ago. One kid, my mother.
Mom and dad have been married for 43 years. Both first marriages. No illegitimate children that I'm aware of. Just me and my sister.
No, my grandmother on my mom's side had 7 brothers and sisters, and most of them had at least one or two kids, and most of those kids have had one or two kids, and most of those have had one or two kids, and some of those may have had kids by now.
I knew all of the cousins in my generation, as we used to do big family get togethers around holidays and such. I haven't kept track of many of them, and almost all of them now have kids of their own that I've either never met, or only saw when they brought them to a family function and I couldn't tell you any of their names or who belongs to who.
